变压器中溶解气体分析与故障诊断

目前现阶段,电力变压器的性能好坏、质量的高低直接影响着电力系统的正常运行,尤其它对电力系统的运行的运营效益和可靠性都至关重要。为了减少变压器不必要的事故造成停用,我们采用油中溶解气体分析(DGA)技术对变压器进行早期的故障诊断,同时也能保证电力系统的可靠、安全的运行。本文主要是结合了油中溶解气体分析技术,对变压器在正常运行的过程中所产生的故障原因和提前诊断的重要性进行了概括、阐述和分析。

Analysis of Dissolved Gas and Fault Diagnosis of Transformer

At this stage,the quality and performance of power transformer directly affects the normal operation of power system,especially it is essential to the operation efficiency and reliability of power system.In order to minimize the unnecessary accidents of transformers,we use DGA technique to make fault diagnosis of transformer in early stage and guarantee reliable and safe operation of the power system.This article combines the DGA technique in gases dissolving process and makes overview,elaboration and analysis to the causes of failure and the importance of early diagnosis.
